I have a command (cmd1) that greps through a log file to filter out a set of numbers. The numbers are
in random order, so I use sort -gr to get a reverse sorted list of numbers. There may be duplicates within
this sorted list. I need to find the count for each unique number in that list.
For e.g. if the output of cmd1 is:
100 100 100 99 99 26 25 24 24
I need another command that I can pipe the above output to, so that, I get:
100 3 99 2 26 1 25 1 24 2
